Title: Semiconductor device
Inventor: TSUCHIYA CHIKARA
IPC: H03M1/12
Filed: 1991-03-20
Abstract: PURPOSE:To improve the accuracy of A/D conversion by making a current supplied from an input terminal to transistors(TRs) of two sets of differential amplifiers operated simultaneously in differential operation by a sample-hold signal at the sampling equal to that at the holding. CONSTITUTION:A circuit A composed of two sets of differential amplifiers is the sample-hold circuit. When a switching signal S2 is set to an H level at sampling, a sample transistor(TR) Q1 and TRs Q3, Q5 of the differential amplifier are turned on, the sum IA of a current I1 of a constant current source, a collector current I3 of a TR Q5 and the base current of the TR Q1 (IA=I1+I 3+I2/hfe) flows to an output TR Q. When a switching signal S1 is set to an H level at holding, TRs Q2, Q4 are turned on and a current IB=I1+I2 flows to the output TR Q. Since the current I2/hfe is small, the current and the output voltage of the output TR Q at sampling are made equal to that at holding by selecting the current I2 to be equal to the current I3 and then the accuracy of A/D conversion is improved.

Inventor: TAKAMURA JUNYA
IPC: F02D15/02
Filed: 1990-03-08
Abstract: PURPOSE:To reduce the quantity of remaining combustion gas by reciprocating a piston so that the combustion chamber-volume at the time when the piston is at top dead center after the completion of exhaust stroke is constantly smaller than the combustion chamber-volume at the time when the piston is at top dead center after the completion of compression stroke. CONSTITUTION:One end of a connecting rod 2 is connected to the off-centered position of a gear 3, and the other end is connected to a piston 1. A crank 4 is connected to the rotary shaft of the gear 3. The gear 3 is then brought into mesh with a gear 5 having a diameter 3.5 times that of the gear itself. Thus, the piston is reciprocated in a cylinder 7 so that the combustion chamber- volume at the time when the piston is at top dead center after the completion of exhaust stroke is constantly smaller than the combustion chamber-volume at the time when the piston is at top dead center after the completion of compression stroke. The combustion gas remaining in the combustion chamber-space can thus be exhausted much more by the piston 1.

Title: Developing method
Inventor: TSUKADA HARUO
IPC: G03G13/09
Filed: 1980-05-02
Abstract: PURPOSE:To prevent a reduction in the image density even after long-time development by applying no magnetic field to the latent image developing region of a developer holding means (developing sleeve) set opposit to a latent image retaining means (photoreceptor). CONSTITUTION:Developing device 5 provided with sleeve 2 is installed in opposition to electrostatic image retaining means 1. By setting magnet 8 regulating the thickness of developer 6 so that is does not reach the surface of means 1 and magnetic blade 4, no magnetic field is applied to the region where a latent image on means 1 is developed practically, that is, the narrow spacing region between means 1 and sleeve 2. Toner having larger particle size in magnetic developer 6 is apt to remain in the developer with the lapse of developing time and begins not to contribute to development. As a result, the image density is reduced after a long time. By this method the reduction is prevented. By applying a bias voltage between means 1 and sleeve 2, toner is easily deposited on a latent image on means 1.
